macadamia and raspberry blondie

macadamia and raspberry blondie

• 14 Jul 2025

Last month I borrowed Michael James excellent baking book, Sweet Seasons, from the library. I bookmarked quite a few recipes and for my first bake, I decided to make a batch of macadamia and raspberry blondies topped with caramelised white chocolate ganache. Whilst I am not a regular chocolate fan, I've always loved white chocolate in all its forms and in particular, caramelised white chocolate.

It's raspberry season here, so fresh berries abound but for baking I prefer to use frozen berries. Michael suggests using rhubarb when raspberries are out of season. Just gently poach it in a not-too-sweet sugar syrup - you want the acidity of the rhubarb to meet the sweetness of the white chocolate. Pistachio and rhubarb are also a wonderful combination, so consider switching out the macadamias as well. A slightly different version of the blondie can be found here, on the Delicious website.

Here's the recipe for you, adapted from Sweet Seasons, which makes a 7-inch square blondie. My blondies were pretty chunky, so I think you could also bake the blondies in an 8-inch square tin or a slice tin, but it might take less time to bake. For all my recipes I use a 250ml cup and a 20-ml tablespoon, unsalted butter and 60g eggs. My oven is a conventional gas oven so if your oven is fan forced you may need to reduce the oven temperature by 20°C.

Macadamia and raspberry blondie - makes 12 blondies

Ingredients

215g spelt flour

slightly heaped 1 tsp baking powder
3/4 tsp fine sea salt
1 and 1/2 tbs malted milk powder 
145g unsalted butter, softened
145g dark brown sugar
75g whole egg, at room temperature (1 and 1/2 eggs)
1 and 1/2 tsp vanilla paste
85g toasted macadamias, roughly chopped
75g white chocolate bar cut into chunks
100g raspberries, fresh or frozen
grated zest of 1 lemon

Caramelised white chocolate ganache
125 g caramelised white chocolate bar
125 g cream

To decorate (optional)

Freeze dried raspberries

Method

Preheat the oven to 170°C, fan forced. Grease and line a 17 x 17 cm baking tin or a slice tin with baking paper.

Ganache

Finely chop the caramelised white chocolate bar and place into a heatproof bowl.  Place the cream in a small saucepan and bring to just below the boil, then pour the cream over the chocolate. Set aside for 5 minutes, then stir until smooth. Set aside at room temperature until it becomes a thick, spreadable consistency. You can refrigerate the mixture to speed up the process.

Blondie

Whisk the flour, baking powder, salt and malted milk powder together in a medium bowl to combine and knock out any lumps.

In a stand mixer fitted with the paddle attachment, beat the butter and brown sugar on medium speed for 10 minutes, until pale and light. Scrape the side of the bowl with a spatula, then add the eggs and vanilla and beat until just combined.
Add the flour mixture in two stages, beating at each addition until just combined, and scraping down the side of the bowl as required. Add the macadamias and white chocolate chips and mix until just combined. The mixture will be thick.

Transfer the mixture into the prepared tin and spread it out evenly with a spatula. Place the raspberries evenly over the top. Bake for 25-30 minutes on the centre rack or until the blondie is golden on top, and a skewer inserted into the middle comes out clean. Transfer to a wire rack to cool.

Once cool, spread the ganache over the blondie, sprinkle with freeze dried raspberries, if desired, then cut into slices for serving.

Store in an airtight container at room temperature for up to 5 days. 

These were very luxe and now I can't wait to make a rhubarb and pistachio version.

See you all again next week with some more baking from my kitchen.

Bye for now,
